So you're an enthusiast not looking to purchase? I think you're wise in your idea to pursue the purchase of a home instead of a car for very obvious facts and reasons.
Me on the other hand, though I foresee the pitfalls of not saving up and buying a home I'm a little more philosophical in my reasoning to pursue a purchase of a sports/sporty car; simply, I love cars. I have ever since I was a child, "car" was my first word (ask my Mom if you don't believe me). For me cars are so much more than a means of A to B, they're life, life on the open road. A place where I feel most at home, and a car that makes the most of that experience is the right car for me. Sorry for a the philosophical rant, but I'm sure you catch my drift by now.
